The game has no bring in, no ante. Regular 5/5 blinds with a straddle or mississipi sometimes. It's a very loose game.

We choose our doorcard on 3rd and discard 2.

Max bet/raise on 3rd is 30 or pot (if pot is less than 30)
60 on 4th
90 on 5th
120 on 6th
150 on 7th

Would you raise, limp or fold 8s7s6s utg 7 handed?

Everyone choose his door card on his turn to act so I can't see any door cards.

I would limp and hope to back raise. All our potential door cards could be part of a weaker low draw, so smoother lows will likely raise and we may get more multiway action with a limp than a raise.

Is it that strong in super stud?

A small suited three-straight-flush is the strongest possible starting hand, both for playability and native strength.

wow, UTG seeing no hole cards. sounds like a fun game. having never seen this structure before, I think you probably have to limp a huge portion of your range UTG given the lack of information, but yeah, definitely play 876sss.

You describe it as a loose game, so initially you're representing a range that includes medium gapped hands like 864 or 753 by limping. Hands like 234 or Aww might well raise for value, and once a few people have thrown in that first chip, they're not folding when you back-raise. With a hand like this you want to start with as big a pot as possible, and that ought to do it.

Many hands will brick out and not contribute later, so now, while everybody imagines a bright future, is the perfect time to get more bets out of everybody. In contrast, any card Ten or below, and any Spade will improve your hand at least a little, so you are not going to brick out all that often and will retain or improve your equity.

And if you do catch QJdd or some other nonsense big cards, then you will have an easy decision on the big bet streets. I mean, with a hand like this almost all your decisions will be easy. Occasionally you'll make a marginal one-way hand, like a bad Eight or garfunkle two-pair, but you shouldn't lose a lot of money with hands like that or you're doing something else wrong.

I would not limp any 864 and 753 only if suited.
Thank you for your input, I will apply this strategy next time

In a loose game with that structure, if you can get in for a limp one bet, I would play almost any 3-flush low hand. Want to see how the hands develop on 4th and 5th street.

If there's any chance people can put you on a high-only hand, roll the 8, otherwise roll the 6.

I try to play all third streets the same way, so if I usually limp, then I limp with all my hands. If nobody ever pays any attention, then it's OK to play your Strong hands strong and you weak hands weak. Of course, once the raising starts it's OK to join the crowd.

But if one person is paying attention, that's all it takes. One person is perfectly capable of announcing to the table, "Look who brought it in for a raise. He never does that." Then you're toast.

8s7s6s is the hand I dream of and pray for in these games.

Isn't A23s much stronger?

A23s has about the same native strength, but for playability give me the 876s. It makes more straights, and often picks up valuable deceptive equity with Tens or Nines, cards unlikely to get hands like trips or low draws to fold.

You're right. I was talking about utg when you're first to act and can't see any doorcard.

What about hands like JsTs9s, would you call a raise if multiway and our outs are live?
What about AsKsQs ?

I think, they are trash hands but when 6 people limp in front if you and they all show low cards, JdTd9d may be worth limping or even call a raise. I'm not sur because most players play passively on 3rd, I can easily run into better flushes which are not playing for half the pot.

I would need perfect circumstances to play any three flush without an Ace or 3-low, limping into a multiway pot with live outs seems fine. Calling a raise when we could get backraised would not.
